Tollgrade Expands the LightHouse® Grid Modernization Platform to 50Hz for Europe and Asia

RESTON, Va., April 3, 2013 /PRNewswire via COMTEX/ -- Tollgrade Communications, Inc., a global leader in providing network assurance solutions to the world's largest utilities and telecommunications providers, today announced that a new 50 hertz version of its industry-leading LightHouse Medium Voltage (MV) sensors is now available in Europe and Asia. The company announced today in a separate press release that Western Power Distribution (WPD), one of six Distribution Network Operators (DNOs) in the United Kingdom delivering electricity to more than 7.7 million customers, is the company's first European installation. With this deployment, the LightHouse platform is providing WPD with real-time visibility into its distribution grid, allowing grid operators to improve reliability and optimize network planning during their transition to a low-carbon future.

With growing demand in Europe and the need to evolve generation from fossil fuels to clean technologies like solar and wind energy, the grid is getting stressed beyond its limit. It is already estimated that outages cost Europeans EUR 150 billion[1] annually, the price tag of power quality issues to businesses and consumers is around EUR 10 billion[2] annually and that a smart grid capable of reducing loss and improving efficiency would save the EU EUR 52 billion.[3] "Reliable energy is one of the greatest long term indicators of a country's potential economic growth. At Tollgrade, we believe reliability begins to increase as visibility into the distribution grid improves," said Erik Christian, Vice President of Smart Grid at Tollgrade. "By combining medium voltage sensors with predictive analytics software, our LightHouse platform provides visibility with actionable intelligence allowing DNOs to improve their grid reliability and efficiency." The Tollgrade LightHouse platform consists of: -- Medium Voltage (MV) Sensors: inductively powered with flexible communications offered through cellular or WiFi with operations down to three amps. Key sensor measurements include: load current, fault current, electric field strength, power factor, phase angle, sags, surges, wire temperature and harmonics.

-- Predictive Analytics Software: LightHouse Sensor Management System (SMS) software classifies grid conditions linked to map-view displays to give utilities the situational awareness needed to quickly respond to load planning, outages, and power quality challenges.

Leading the Industry in Distribution Grid Visibility Combined with Predictive Analytics Tollgrade leads the industry by providing distribution grid sensors that deliver visibility down to three amps and are inductively powered to eliminate the maintenance costs that are required to support battery powered alternatives. Unlike first-generation fault indicators, the LightHouse platform combines its industry leading sensor technology with predictive analytics software to classify grid conditions with visualization tools to give grid operators the situational awareness to not only pinpoint the locations of problems but the background data needed to analyze "cause and effect" behind distrubances like equipment failures. Within the software, customizable rules can be defined to alert utilities to inefficient operating conditions, subtle system failures, or indications of anomalous behavior that are early indications of future outages. The software recognizes and can report on the cause of these inefficient grid conditions including load imbalance, blown lateral fuses and improper coordination of circuit protection timing.

The platform allows utilities to: -- Reduce customer and system outage minutes -- Detect overload on substation transformers -- Find imbalance on circuits -- Reduce technical loss -- Monitor high-value assets -- Know if circuits are operating properly -- Find and resolve chronic power quality issues The LightHouse system easily integrates within a utility's existing infrastructure and back office systems. DNP3 interfaces support multiple masters to SCADA systems, Historians, DMS, and other systems.

Delivering First Class Communications With WebRTC

This webcast captures a recent discussion about WebRTC between Jim Donovan, Director of Product Management at Oracle and Larry Hettick, Editorial Director and Senior Research Fellow at Webtorials. The topics cover WebRTC reliability, interoperability, and security--looking at how Oracle addresses these issues.

Oracle in Enterprise Communications

Most in the industry have heard of the acquisition of Acme Packet by Oracle. What you may not know is that Oracle has a number of telecommunications products including a UC suite, WebRTC Session Controller, and Operations monitoring tools. Oracle is pursuing both the enterprise and service provider.

Featured Whitepapers

ConnectCare & Unified Contact Manager

SPAN's ConnectCare is a WebRTC-based telemedicine app, which allows consumers to easily and instantly avail clinical healthcare from the providers, regardless of their location. This app is extremely useful to healthcare providers, patients and their caregivers alike.

WebRTC Security Concerns

This whitepaper covers two of the most relevant topics in communications industry today: WebRTC and security. We will introduce the problem of security in WebRTC including those traditional VoIP attacks that are going to be present in WebRTC services. Later we will mention ad-hoc WebRTC attacks and protection mechanisms, to close with an overview of identity management solutions.

Migrating Real Time Communications Services to the Web

In the Internet age, businesses that own fixed and mobile communication networks, including traditional Communications Service Providers (CSPs) of all kinds, are being challenged with some tough questions: How do we stay relevant to our customers?

Delivering Enterprise-Class Communications with WebRTC

WebRTC is an emerging industry standard for enabling Web browsers with real-time communications capabilities. It enables enterprises to enhance Web sites, empower BYOD users, and improve video collaboration and on-line meetings, to name but a few examples.

WebRTC Report Extract Reprint

This document examines the growing important of WebRTC, both generally and for telecom service providers. It considers the expanding range of use-cases, the multiple layers of interoperability likely to be desired by telcos, and some implications in terms of network integration and mobility.


Robust Enterprise Grade WebRTC Systems and Services

The emerging WebRTC standard has become one of the industry's hottest topics – and with good reason. Being able to "communications enable the web" has Communications Service Providers as well as Enterprises busily making plans for deployment. But, as these plans unfold, reality is starting to intrude on those plans. Our expectations of telephony services are much higher than web browsing. We expect the phone to connect instantly, operate with minimal disruption, and work seamless across any network, anywhere, at any time. There is also an understanding that phone service is inherently secure. With WebRTC, the expectation is for these applications to behave in the same manner.

This session looks at the user experience and expectations of a WebRTC Enterprise service. It will also cover how a WebRTC enterprise handles security, reliability, and interoperability within browsers and networks.


The Oracle Communications WebRTC Session Controller enables communications service providers (CSPs) and enterprises to offer WebRTC services – from virtually any device, across virtually any network – with carrier-grade reliability and security.

- Summary


Communication Service Provider (CSP) voice service revenues continue to face pressure due to shifts in communication preferences and competition from non-traditional service providers. Voice communications are now often embedded into applications outside the domain of traditional telephony voice usage. CSPs have been challenged to effectively leverage and monetize new web-oriented communications technologies.
